EECIFIGATION forming part of Letters Patent No. '?54=,599, dated March 15, 113063 Application filed August 24., 1903. Berial Bio- 170,506, (No model.)

To all whom it may concern:

Be it known that l, FRANK NOVOTNY, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State ofMinnesota, have invented certain new and. useful Improvements in Guns, ofwhich the following is a specification. i

My invention relates to improvements in guns; and it consists particularly in the construction and arrangement of hammers and actuating parts whereby the eifectiveness of the hammer action is increased and the parts are arranged in a smaller compass and within the main body oithe frame to avoid the necessity of-cutting away'and weakening the stock or the forward extension of the frame.

To this ehd my invention consists in the features of construction and combination hereinafter particularly-described and claimed.

In the -accoi'npanying drawings, forming part of this specification, Figure 1 is a top view of the gun-frame. Fig. 2 is a section on line as w of Fig.1 with the parts in firing position. Fig. 3 is a similar view showing the hammers cocked. Fig. i is a view of the trigger-plate. Fig. 5 is a rear view of the frame, partly broken away. Fig. 6 is a front view of the frame. Figs. 7, 8, and 9 are detail views of one of the hammers. Figs. 10 and 11 are views of one ofthe sears. Fig. 12 is a section on line 54 y of Fig: 10, and Figs. 13. and 14 are detail views of one of the sear-springs.

In the drawings, A represents the gunframe, provided with a rearwardly extending tang 2, to which the stock (not shown) is secured. Y

B represents the hammers, each having pivotal support 4 in the frame ofthe gun and being provided with points 5.,which strike the shells in the ordinary manner. The hammers are held in cocked position by means ofsears 6, which have pivotal support-7 in the sides of the frame abeve and at 'therear of the hammere and areeach provided upon their lower ends with a thin'flat lug 8, adapted to engage with a shoulder 9 upon the rear side of the'adjacent hammer, as illustrated in Fig. 3,-to hold the same in cocked position. Each of [the sears is controlled by a split spring 10, interposed between the top of the scar and the-adjacent front wallvof the frame. Each of the hammers' is actuated by'a split spring 11, interposed between .the hammer and the adjacent front wall of the frame, the ends of the spring bearing against the 'wall of-the frame and the hammer below its pivot, respectively. Each hammer isformed upon its front side above its pivot with a boss 12, which strikes against the hammer-actuating spring when the gun is fired to cause rebound of the hammer from the shelLf' 13 represents cocking-bars passing through the forwardly-extending portion 14 of the frame and normally held in restrained position-by surrounding coil-springs 15. The for ward ends of the cocking-bars project into the recesses 16 in the forward end of the frame and are adapted-to be engaged by lugs 17, carried by the rear end of the fore-end iron 18' to force said cocking-barsrearwardly to cook the hammers when the gun is broken, asillustrated in Fig-3, the rear end. of each cocking-bar bearing against the outwardly-extending lugl9 upon theinner side of the adjacent hammer. --Pins 20 project into-slots 21 in the upper sides of the cocking-bars to limit the movement of said bars and prevent their turning. Suitable sear-releasing mechanism is employed, such as the trips 22, having pivotal support. 23 upon the trigger-plate, the downwardly projecting ends of said trips standing in front of the lateral arms 24: upon the sears. The rearwardly-projecting ends of said trips are adapted to be engaged and actuated by the triggers 25, which have pivotal support 26 upon the trigger-plate.

In operation the breaking of the gun, as illustrated in Fig. 3, will force the cookingrods rearwardly to turn the hammers into cooked position, the hammers being held in such position by engagement of the sears 6 with the shoulders 9 upon the rear sides of the hammerathe cooking of the hammers compressing the hammer-actuating springs 11. Upon the scars being released from the hammere by the trigger mechanism the maihsprings 11 will actuate the hammers to carry them into firing position.

It will be noted that the hammers and sears, as well as the hammer and sear-actuating releasing mechanism 1. 'In a gun, in combinationwith the frame,

a pair-inf, hammers pivotally supported insaid frame,' tfertically-amnged split s rings interposed between the fr'pnt's of said each spring bearing against the adjacent wall of the frame'and the adjacent hammer below .its pivot, sears' having pivotal support above said hammers-and means for engagementwith said hammers, and vertically-arrang split springs interposedbetween said sears and the adjanent front wall frame, theends of each spring beating against the front wall of the frame and the adjacent sear, as and for the purpose set forthi."

2. a' gun in combination with the frame. provided witha forward extension, hammers ipivotallyeupported within the body of the frame, verticallysarranged, split springs arranged between the fronts of said hammers and the adjacent frontwall- -,of the frame, the

ends of each spring-hearing fagainst; said front 3 v frame above said hammers'and having means walland against thh'iaQdjaneht hammer below its pivot, searsvpivotallmsupported in. said for engagement with said hammers, and a vertically -arrangedidepending split spring interposed between each sear" and the adjacent front wall of the frame, the ends ofsai'd spring hearing against said front wall and against'the adiacent sear'in line with itspivot.
